This cooperative group activity correlates with Common Core Geometry standards for grades 2, 3, 4, and 5. Students are given a large piece of butcher paper and the attributes to a "mystery shape". Working together, they must figure out what the shape is and then make it as large as possible using yardsticks and protractors to measure. This makes a great project for your bulletin board. A follow-up worksheet (completed individually) is included to assess each student.
